Hi folks, is '0' considered unknown when stacking?

I have 5 DS's, and I'm trying to stack them, most of the time each DS
value is 0.00:

rrdtool lastupdate /var/db/rrd/hdd_tput.rrd
 ada0 ada1 ada2 ada3 ad4

1310189105: 0.00 0.00 0.00 0.00 0.00

When graphing, I use this order: ad4 ada0 ada1 ada2 ada3

I STACK ada0 ada1 ada2 ada3.
If ad4 has a non-zero value, its correct value is graphed, using the
color configured for ada3.
Here are the definitions:

                "GPRINT:ad4:LAST:%4.0lf %s\\t",

                "GPRINT:ada0:LAST:%4.0lf %s\\t",

                "GPRINT:ada1:LAST:%4.0lf %s\\t",

                "GPRINT:ada2:LAST:%4.0lf %s\\t",

                "GPRINT:ada3:LAST:%4.0lf %s\\l"

Example can be seen here http://www.ardynet.com/~ardy/ad4.png

How can I stack each DS?
